Thanks on the comments commentary; I'm a big believer in them too. The best thing I learned on comments is make them read at a higher level than the code they describe.
About the single-file implementation: I had read that templated classes have problems with putting the implementation into a separate file, but I don't remember the specific reason anymore. Seems like it had something to do with the way compilers generate code for each used template-parameter pair.
Have you had a different experience with templated classes? Do they work in a normal two-file header/source layout?
BTW,
Happy Birthday!
